Psychophysical matching techniques were employed to equate the subjective experience of motion in two motion simulation devices - the RATS, a whole- body motion environment and the ALCOGS, which presented motion cues through a moving seat-pan. The psychophysical matching technique was designated SIGMA, for Subjective Interactive Gain Measurement Analysis. Use of the motion drive algorithm, derived using SIGMA, resulted in equivalent roll- axis tracking performance between the two simulators. However, training subjects in the ALCOGS using this motion drive algorithm did not result in better transfer between simulators than training with no motion cues.
